Write the equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8)

Answers

Answer 1
Answer:

Answer:

y=(x)/(0.3)-18 \ or \ 3y=10x-54

is the equation of perpendicular line.

Step-by-step explanation:

We are given , the equation of a line is  y=-0.3x. +6

We can deduce that the slope of the given line is m=-0.3

The slope of its perpendicular line would be , m_p= (-1)/(m) =(1)/(0.3)

Now using the point slope form, y-y1= m_p(x-x1)

Use the given point (3,-8) \ as\ (x1,y1) substituing these.

y-(-8)= (1)/(0.3) (x-3)\ny+8=(x)/(0.3) -10\ny=(x)/(0.3) -18

Therefore the required equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8) is y=\frac{x}{0.3} -18[/tex]

A survey of 46 college athletes found that 24 played volleyball, while 22 played basketball. a) If we pick one athlete survey participant at random, what is the probability they play basketbali? b) If we pick 2 athletes at random (without replacement), what is the probability we get one volleyball player and one basketball player?

Answers

Answer:

A) (11)/(23)

B) (88)/(345)

Step-by-step explanation:

A survey of 46 college athletes found that

  • 24 played volleyball,
  • 22 played basketball.

A) If we pick one athlete survey participant at random,  the probability they play basketball is

P_1=(22)/(46)=(11)/(23)

B) If we pick 2 athletes at random (without replacement),

  • the probability we get one volleyball player is (24)/(46)=(12)/(23);
  • the probability we get another basketball player is (22)/(45) (only 45 athletes left).

Thus, the probability we get one volleyball player and one basketball player is

P_2=(12)/(23)\cdot (22)/(45)=(88)/(345)

The required,  any triangle that has two sides and the included angle between them given can have its area calculated using the trigonometricarea formula.

What is the triangle?

The triangle is a geometricshape that includes 3 sides and the sum of the interior angle should not be greater than 180°

The trigonometric area formula can be used to calculate the area of a triangle when we know the lengths of two sides and the included angle between them. The formula is:

Area = 1/2 * a * b * sin(C)

where a and b are the lengths of the two sides, and C is the angle between them.

Therefore, if we are given the lengths of two sides and the angle between them, we can use the trigonometric area formula to calculate the area of the triangle. This formula is particularly useful when we do not know the height of the triangle or cannot easily calculate it using other methods.

So, any triangle that has two sides and the included angle between them given can have its area calculated using the trigonometric area formula.
